FLUID-PRESSURE GOVERNOR.

Specification of Letters Patent. n Patented Fell), 13, 1917.

Application filed September 22, 1916. Serial No. 121,60 f.

To all lwhom, z't may concern Be itknown-that I, HAROLDA, HAYWARD,

a citizen of the United States, and a resi.-

dent of the city of NewYork, boroufrh of Manhattan, in thecounty and State ofc New York,l`have,invented a new and Improved F1uid-Pressure Governor` of which the following is a full, clear, ,and exact description. This ,invention relates to iluid pressure governors and has particular reference to devices -of this character adapted' to automatically govern the flow of fluid and deliver the same at. aV substantially uniform pressure :materially` reduced from a higher pressure of either regular or irregular tension. V y

More-definitely stated the apparatus disclosed 'herein is` designed more particularly for'reducing the pressure of `gas received at high pressure from'the source of supply and-delivering the gas at a uniform pressure much reduced from the tension or' pressure of the source.

I wish it to be distinctly understood, however, that my device -is Iadapted for use in the governing of other species of fluids, either gas or liquid.

Among the objects of lthe invention is to provi'dejagovernor including a casing havA in'ga'n inlet and an outlet, the'inletbeing guarded by an adjustable valve whereby the volume of the'iiuid admitted into the -casinglmayvbe delicately controlled according to various orlginal pressures.

Another object of the invention is to i111- provey the facilities for delicately adjusting or varying the effective pressure ofthe fluid within 4the casing acting upon the inlet valve.

furtherQ objectoffthe invention is to specifically improve the'construction ofthe inlet` valve -and its Seat, providing vfor a more convenient and effective action ormabase having inle "A still further object is to provide conl trolling' mechanlsm'fincluding a 'ma-in rigid n providedI `for ithepurpose of inclosing'the valve mechanism and carrying means to actuate the 'sameaccording to a desired uniform lo`w pressure 'forthe outlet.

with alo forogoiog ond other objoots in' view,`the invention consists in the arrangeand outlet holes formed' therethrough Witltheir axes verticalpar-4 being ment and combination of parts described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illust rating a practical elnf bo'dilnent thereof rf ference is' had to the accompanying drawi ugs, in which like reference characters de signate the same parts in the several views, and in which- Figure 1 is a vertical central longitudinal section `on the line' l-1 of Fig. 2 of my improved device showing the parts in norinall operative position;

Fig. 2 is a horizontal section on the line 252 of Fig. 1, and indicating the main valve mechanism in plan; y

Fig. 3 is a plan view of the inner valve seat showing the screen therein;

Fig. 4 is a detail 11ew of the diaphragm hanger or `link connacting the lever mech- Aanism'ior governing the position of the inlet valve;- D

Fig. 45 1s a transw rse sectional detail on the line 5-,5 of Fig. 2.

' The spud 13 const .tutes a valve seat, the I' active face `of which s formed with a series of concentric corrug ations orconvolutions 15, the edges of which are ,shown lying in the, same plane and cooperating with a l leather or other soft lompressi-ble gasket 16,

cemented or otherwise secured to the bottom or active plane face o'f the valve 17, re, ferred to hereinafter as. the inlet val-ve.

. The lower end of, the Spud` 13 is counteri bored at 18 toadmi; the inlet pipe 11 and thereby provide a sho ulder or seat- 19 against which a strainer 20 is: secured bythe end-of the inlet pipe.' This strainer has the effect of` modifying to a c1 rtain extent the force ofthe ressurewhile the fluid is on the way throng `'the restrictel inlet 1.13 and it also lservesas dvmeans to prevent any coarse or 'heavypa'rti'cles of extraneous material pass- "ilnto lthe governoi casmg. Y ,l

e ,casing refer] ed to comprises two bottom of theI base stein or spil-d having` an.

outwardly projecting shoulder for clamping the n'iaterial surrounding each ol the holes to the base. Gaskets 225 of any suitable naturc may be provided to make tight joints at these points. It will be observed that .one

o f the spuds is located centrally of the cas- ,10-ing, while the other, is adjacent one side thereof. rl `he base is substantially co-extensive with the inside of the bottom section of th'e casing. One end ot' the inlet valve 17 is disposed close to or abutting against the 2,5 inner vertical wall of the casing section 21, whereby the valve is retained in definite position'and held from rotation around the verticalV axis ofthe valve seat by contact be-V tween the curved casing wall and the curved 3o end of the valve plate.

A. pair o' 'lugs or standards 24 carried by the basevextend upwardly therefrom close to the valve scat 13, but between the valve seat and the central spud l1'. The upper ends of H5 these standards .are provided with horizontally alined holes through which a pivot pin projects, the of the pivot pin be lng perpendicular to a straight line and joining the centers of the spuds. A standi `ard 0r lug 26 is carried by the opposite end of the base and extends upwardly .therefrom 'and has a hole through whirl: a' pivot pin 2 7 projects with its axis parallel lo the axis of the pin 25. j

The base, through the lugs just described, carries a levermechanism of any suitable nature for controlling the 'posit-ion of vthe inlet' valve 17. .herein and ot' a preferred:nature includes H50.` si lever- 28 of the first class" iournaled upon the pin 25 and having ball and socket con.-A

-nection 29 at its short arm 4with the effec? tive center of the inlet 1T. Thisconnection with the inlet valve preferably includcsa threaded stem acting` through a main s\ l pvortg nut E5() below the end oi the anni', 'saldf'steni luivlnga slot ill in its upper end for rotating t-'llej stein- 1.o vary vthc effective length ot'the stem, a loclnut 32 being-proce videdto make-. suclr adjustment permanent. In this connection rl. is to be' observed that 'i theflever 28 is preferably i'orined'of sheet" metal, suflicient' stillness 'being provided by forming two downwardly projecting flanges of the 1u twhich said-.screw cooperates to bind a The lever nucluinism shown 28. The nut 30 ts between these flanges at 65 the short end of the lever and thereby is held from rotation while Athe stem is being turned. That portion of the lever 2S through which the pivot pin'25- passes is ot' wider structure than the end portions 70 -whereby a greater stability for the lever is realized. The longer end .or arm of the lever 28 has its downwardly projecting fianges 28' provided with longitudinal slots 3&5 which extend jractically from the extreme end 28 of tlielever adjacent the lug 2li, inwardly toward'the center of the lever system.A These slots are in horizontal alinement with cach other.

A secondary lever- I-ll ot the second class. is pivoted atone end on the pin QZwhile its fre(` end is located approximately in the vertical center of the system and is pivotally connected to the lower end of a' diaphragm hanger or link The-lever 34 comprises parallel sideanges lying in vertical planes on v opposite Sides of the longer end of theiever 28, said flanges being connected to eachother at their pivoted end by` a yoke 3(3 spanning the upper end 26. Eachof the-flanges of the lever 34` 1sl individually pi'voted to one of -the downwardly projecting legs 35 of the hanger 'bym'eans of a short pivot 37. The.

free end of this 'lever 3 4,. therefore, has free movement np and down with respect to theiadjacentv part of the primary 'lever 2 8. The hanger. is shown 'in detail 1n Fig.

4 and 'comprisesl'in addition to the legs 35'-, a plate 35 having a central hole for a screw or other-suitable fastener 38, upon opposite sides of which are formed a pair of .lugs 39 struck. downwardly and providing a seat for a non-rotary nut 40, with weight or disk 41 to a flexible partition u n .l or diaphragm 42 secured firmly in place between the flanges 43 formed upon and extending outwardly from the casing sections 2l and 22.

These flanges are preferably'beaded, as indicatedat` 43'; for the purpose-of stiilfening the saine and throughl which fastening means 44 pass t-o lock' the parts of the'casin'g together. i

i The parallel tlanges constituting the lever .or l'ink 34 are-provided with p airS ofoppositely alined holes 4-5, aserles of Such pairs of holes extending practically from une end of the vlever to thev other. A cou` 'pling pin 46 is passcd'through any selected 120 pair 'of holes 45 and the registering slots.

33 ofthe primary lever, the'position of the. coupling pin`.with respect to the Secondary lever determining the .effective ratio bef' I tween the power end' of the lever 34 and the 12S .valve end of the'lever 28.. The vertical movement 'of .thehanger 35 isnever very excessive, and hence them'ovcmentrof the Lineale` hanger in an are of a circle around the axis of the pin 27 may easily be accommodated by slight looseness 'in the pivot connections. Anyr of the pins 25, 27 or 46 may borprovided at one end of thev finger piece foiconveniencel in manipulation and held temporarily in operative position by any suitable `form oftemporary fastener,` such' asa cot-lar pin 47. i The force of the weight 41 may be increased if desired by a spring 48 held centrally thereof by means of an adjustable screw 45) tapped through the center of the upper easing section 22 and held in place by a lock nut ll'to malte such adjustment effective.` This center screw lil is provided with a vent 51` to maintain `the upper portion of the casing under atmospheric pressure. I wish to emphasize that the adjustment of the inlet valve through the stem 29 provides for variation in the volume of fluid admitted into the casing; the adjustment of the screw 49 provides for a' variation in the effective force of the counter4 balance means acting upon the diaphragm, and the adjustment'of the eoiipling pin 46 along the slots 33 provides directly for variation in the effective pressure of the diaphragm mechanism.
